Hey there!
We are given that :
22+4=24
13+6=16
80+2=82
67+9= ?
We will observe the pattern followed in the first and then Use it to find the last .
22 + 4 = 26 ( But here it is 24 ) ( Difference between original and given = 2 )
13 + 6 = 19 ( But here it is 16 )( Difference between original and given = 3 )
80+ 2 = 82 ( Given the same) ( Difference between original and given = 0 )
We don't see a same pattern. Let's look for something else :
22 + 4 = 20 + 2 + 4 = 20 + ( 2 + 4 ) = 20 + ( 4 - 2 ) = 24
13 + 6 = 10 + 3 + 6 = 10 + ( 3 + 6 ) = 10 + ( 6 - 3 ) = 13
80 + 2 = 80 + 0 + 2 = 80+ ( 0 + 2 ) = 80 + ( 2 - 0 ) = 82
This too doesn't match. We will look for something else !
22 + 4 = ( 22 + 4 ) - 2 = 24
13 +6 = ( 13 + 6 ) - 3 = 16
80+ 2 = ( 80+ 2 ) - 0 = 82
We found out a pattern.
The given numbers are first added then the units place digit of first number is subtracted from the sum.
So,
67 + 9 = ( 67 + 9 ) - 7 = 69 .
Therefore, 22+4=24
13+6=16
80+2=82
67+9= 69
